Source of “fat-soluble” vitamins

Detailed explanation-1: -Fat-soluble vitamins play integral roles in a multitude of physiological processes such as vision, bone health, immune function, and coagulation. This review discusses the biochemistry, transport, and roles of these vitamins highlighting deficiency syndromes and potential toxicities.
Detailed explanation-2: -Vitamins A, D, E, and K are fat-soluble.
Detailed explanation-3: -Fat-soluble vitamins will not be lost when the foods that contain them are cooked. The body does not need these vitamins every day and stores them in the liver and adipose (fat) tissue when not used.
Detailed explanation-4: -3.1 Lipid Soluble Vitamins These vitamins are not absorbed directly into the blood stream but are absorbed into the lacteals in the small intestine via chylomicrons, transported through the lymphatic system and then released into the blood stream (Kalepu et al., 2013).
Detailed explanation-5: -Functions of Lipids in the Body: Aiding Digestion and Increasing Bioavailability. The dietary fats in the foods we eat break down in our digestive systems and begin the transport of precious micronutrients. By carrying fat-soluble nutrients through the digestive process, intestinal absorption is improved.
